"I've only played on big courts here. I'm pretty pleased with that," Dimitrov said. "I'm not going to shy away from Centre Court. I've played there before, I've won. I know my way now to the Centre Court, not like the first time I walked out."

Dimitrov defeated Andy Murray on Centre three years ago, suggesting his confidence is not misplaced bravado.
